[Bone Tomography Scan Optimization in SPECT/CT Equipment of Nuclear Medicine]
Objective:
To study and search for a balance between the image quality and acquisition speed in tomography of whole body bone scan.
Methods:
Adjustments of acquisition conditions were carried out gradualy every two months since April 2014. The qualities of fused SPECT/CT images were diagnosed by three doctors. Then the picture would be evaluated comprehensively by analyzing image quality and image resolution after adjusting image acquisition conditions.
Results:
Seven kinds of image acquisition conditions taken were in line with diagnostic requirements. The third method is extended to clinical work best.
Conclusion:
To obtain a high colection effi ciency, parameters of bone tomography acquisition can be set a frame of 5 seconds, total 64 (5.625o), automatic probe close and continuous scanning. Also recommends the use of "continuous" instead of "step and shoot" approach in bone SPECT acquisition. tomography, emission-computed, single-photon, bone tomography, program optimization.
